Just thought I would chime in.
There are plenty of companies out there doing wonderful table top rpgs that have nothing to do with 3rd or 4th edition too.
Cortex comes to mind. Hero, Gurps, CofC, Savage Worlds, etc.. etc...
In fact there are more game systems to choose from now than ever before.
I think the sad truth today is that if WotC vanished in a puff of blue smoke tomorrow that gaming would absolutely continue and would continue to grow without them. So I am not at all worried about what happens with 4e. I mean don't get me wrong. I wish the very best for everyone at WotC. I hope they thrive and grow and do just awesome. Same for everyone else out there.
Still. The choices today are vast.
As far as the print thing goes a few of us total rebels have our own print ability. I do my own books with my own two hands. So not only do I not have to wait for turn around on a POD order when I get a customer order I can print it, quality check it and ship it off to them overnight with a couple of days. Printing has come a long way and you don't need a printing press to be able to do short runs of booklets, comic books or even signature bound soft cover books any longer. It is just a matter of having a little creativity, a little skill / experience and a few handy tools.
Not everyone works in their own print shop but I'm just saying there are options out there guys. Always options. POD is not the last word if you are willing to get creative.
